And I imagined that these industries, these manufacturing plants, would be the material symbols that the 20th Century would bequeath the future, deposited in the scenery; traces of the labors of man, and a kind of culture: the pyramids of our age. I was moved by this thought. I kept my distance, attempted to stand back, and took my photographs.
